目的由于角膜放射状切开术(RK),准分子激光角膜表面切削术(PRK),准分子激光原位板层角膜磨镶术(Lasik)和角膜矫形学(Ortho-K)角膜屈光矫正术存在副作用和并发症,所以笔者认为不宜应用于空军飞行人员。笔者就如何在招飞体检中识别接受RK,PRK,Lasik或Ortho-K治疗眼进行了探讨。方法聚光灯角膜照射法,裂隙灯角膜透照法观察角膜情况;人工检影及电脑验光确定屈光状态,观察影动性质。结果在观察对象中,施行RK术4人(占0.11%);施行PRK术7人(占0.19%);施行Lasik术2人(占0.054%);接受了Ortho-K治疗5人(占0.14%)。结论RK手术由于切痕明显在招飞体检中容易识别。PRK和Lasik通过重塑角膜前表面曲率,对于低度屈光不正稳定性好,裂隙灯下也难以看出手术痕迹,识别有一定难度。可通过辨认Haze和检影时的球面差影动帮助识别。使用角膜接触镜者易被检出。PRK,Lasik和Ortho-K均存在视力提高与屈光度改善不平行的情况,用电脑验光仪有助于识别。建议在招飞体检中配置角膜地形图仪,用以观察鉴别角膜治疗前后的角膜地形图形态。此外,把好初检视力关,对于视力在0.9以下者应坚?
Objective To evaluate the effect of corneal radiofrequency ablation (RK), excimer laser corneal topography (PRK), Lasik and Ortho-K corneal refractive surgery There are side effects and complications, so I think it should not be applied to Air Force pilots. The author discusses how to identify RK, PRK, Lasik, or Ortho-K treated eyes during a physical examination. Methods Spot corneal irradiation and slit lamp corneal transillumination were used to observe corneal conditions. Artificial retinoscopy and computerized optometry were used to determine the refractive status and to observe the nature of opacity. Results Among the observed subjects, 4 were RK (0.11%); 7 were PRK (0.19%); 2 were Lasik (0.054%); those receiving Ortho-K Treatment of 5 people (0.14%). Conclusions RK surgery is clearly identifiable in cut-off examination due to the incision. PRK and Lasik through the remodeling of the curvature of the anterior corneal surface, for low refractive error stability is good, it is difficult to see under the slit lamp surgery marks, identify a certain degree of difficulty. Haze and retinoscopy by identifying the spherical aberration movement to help identify. Use contact lenses are easily detected. PRK, Lasik and Ortho-K both have vision improvement and refraction improvement is not parallel to the situation, with a computer refractor helps identify. Proposed in the examination of the corneal topography mapping device to observe and identify corneal topography before and after the morphological changes. In addition, the first screening of good eyesight, visual acuity below 0.9 should be Kennedy?
